The evolution of systems during their operational lifetime is becoming ineluctable. Dependable systems, which continuously deliver trustworthy services, must evolve in order to comply with changes having different origins, e.g. new fault tolerance requirements, or changes in available resources. These evolutions must not violate their dependability properties, which leads to the notion of resilient computing. This paper presents a methodology for developing adaptive fault tolerance mechanisms, from the design to the actual runtime reconfiguration, leveraging component-based middleware which enable fine-grained manipulation of software architectures.
